Theinvention relates to improvements in refrigerator car drains.

Heretofore considerable difficulty has been experienced with therefrigerator car drains incommon and much damage and loss to railroadshave been incurred through the flooding of cars due to stoppage of thedrain pipe which inthe ordinary yconstruction in present use has aninteriorly arranged trap `which cannot be seeiiand vinspected and which'has to be cleaned by a rod. Furthermore with the drain in. ordinary useit is `customary in cold weather to plug up the drain pipe with waste orstraw which is fre thereby causing a flooded car that is notdiscovereduntil the car reaches its destination.

The object of the present invention is to obviate the aforesaidobjections and improve the 'construction of refrigerator car drains andto provide a simple, practical and comparatively inexpensive drainhaving an eX- teriorly arranged trap adapted Ato be readily inspectedand cleaned if necessary.

A further object of the invention is to provide arefrigerator cardrain., adapted through the motion of a refrigerator car toautomatically throw out any accumulation of cinders or the like so thatcleaning of the drain will be renderedfunnecessary.

l out in the claims hereto appended, it being Another object of theinvention is to provide a refrigerator car drain adapted to vary thesize of the outlet or discharge and also to entirely close the sameduring winter and thereby obviate the necessity ofy plug` ging the drainof a refrigerator car. f

With these and other objects in view the invention consists in theconstruction and novel `,combination and arrangement of partshereinafter fully described, illustrated in the accompanying drawingsand pointed understood that various changes iii the formtproportion andminor details of construction may be resorted to without departing fromthe-,spirit or sacrificing any of the advantages of the invention.

. In the drawings Figure 'l is a side eleva,- tion of a refrigerator cardrain and air eX- cludenconstructed in accordance with this invention, Fig. 2 is an end elevation of the same, Fig. 3 is a central longitudinalsectional view of the refrigerator car drain.

and air eXcluder, Fig. Atis a horizontal sectional view takensubstantially on the line LT-4 o f Fig. 3, `Fig. 5 is a detail sectionalview illustrating the construction of the catch for locking the troughor chute of the drain in its adjustment.

Like numerals of reference designate corresponding parts in the severalfigures of the drawings.

In -tlie accompanying drawings, l desig- I nates a drain pipe of an icebunker or compartment of a refrigerator car, not shown,

provided with a iiared upper portion 2 con- `nected to and preferablyformed integral with a horizontal plate 3. The drain pipe l and theplate 2 may be constructed of malleable metal or'any other suitablematerial which is also true of the other parts of the device as anysuitable material may be employed in the construction thereof.4

Thetop plate 3 is provided with bolt openings for. the reception ofbolts 4 arranged vertically and also passing through slots 5 of stems orattaching portions 6 of clamping members which have approximatelysemi-circular yportions 7 forming bearings and adapted to support alow'er tubular sec* tion 8 composed of an upper cylindrical portion 9, alower rectangular or square portion 10 and a horizontal plate or flangel1 arranged upon and supported by the semi-circular bearing portions Theclamping members are angularly bent at l2 to form shoulders for engagingthe edge of the plate or flange which is preferably circular to enablethe lower tubular section and the trough or chute 14 carried by thetubular section to rotate whereby the trough or chute is prevented frombeing brushed oif should it come in contact with an lobject when turnedtransversely of the car. The outer portions of the shank (i are'providedwith perforations i5 for the recepn tion of screws or other suitablefastening' end of the same and is arranged in spaced justment by meansof 'acatch consisting of a relation with the said cylindrical portion 9as clearly shown in Fig. 3 of the drawin s.

The lower rectangular portion 10 o the lower section has straightparallel sides and \it is tapered to form lower inclined edges 16 at thesaid sides to coact with the `bottom 17 of the trough or chute which isarranged at an inclination and whichis movable to adjust the bottom 17toward and from the inclined edges 1G to vary thesize, of the open-yings ofthe lower section of the drain and also to close the drain whendesired to obviate the necessity of plugging the same.

at 18 to the lower rectangular portion of the,4

tubular section 8 and it is secured in its adspring actuated bolt 19located at ,one side of the trough and adapted to engage any one of' anarcuate series of' perforations 20 formed in one of the vsides of therectangular portion of the lower tubular section. The bolt 19 isprovided at its outer endwith ahead 21 and it is ur ed inwardly by acoiled spring 22 arrange which has an attaching plate or' flange124=secured-to the adjacent side of thev troughy 14. The tubular casing orhousing ispro-4 vided with an outer end wall 25 through which the boltpasses and the spring is interposed between the end/Wall and a pin 26 orother suitable stop. Y

The trough is provided below the rectangular portion 10 with a curvedpartition 27 extending fromA the bottom of the trough to a point abovethe outlet of the lower tubular member 8 and terminating short of theupper edges of the sides and presenting a concaved upper face. vThecurved partition 27 which extends transversely of the trough forms anuppertrap receptacle for holding the water resulting from the melting ofthe ice to submerge the lower end ,ofA

the tubular section 8. Also the drainpipe by extending below the upperedge of the cylindrical portion 9 enables the water to. drop clear ofthe sides of the tubular member 8 and prevents accumulation of-ice incold weather which stops the drain pipe now in use. The sides 14 of the4chute/are in suiicient Contact with the side ofthe section 10, toprevent air or gases from passing laterally through the opening formed,between the bottom 16 of the section 10 and the chute 17. Any cindersor similar accu-y mulation .lr-ollecting in the trap will be within atubular casing 23' jarredor jolted out of the same by the motion of the.car. The transverse partition may be omitted if desired. Also the opentrough is adapted to afford ready accessto the trap and will enable anyaccumulation of ice in cold weather to-be readily removed.
